Application filed. December 9, 1927. Serial No. 238,865.

Ihis invention relates to improvements in shovels or scoops and the invention is particularly applicable for use on coal shovels employed for loading coal in mines.

It is among the objects of my invent-ion to provide coal shovel of customary shape and form which shall be provided with a roller member on the heel or back side of the shovel to facilitate pushing it over the rough. mine floor and to prevent the wearing out of the heel which is the portion subjected to the greatest wear.

Another object of the invention is the provision of an antifriction member for a shovel which shall be of simple, durable, mechanical construction and which shall be readily applicable for use on standard forms of shovels without any modification or change and which'shall be so designed as to be practically indestructible.

In. the accompanying drawings constituting a part hereof and in which like reference characters designate like parts, Fig. 1 is a side elevational view of a shovel embodying the principles of my invention; Fig. 9. a front plan view thereof; and Fig. 3 an enlargcd detail view oft-he roller member illustrating its application to a shovel.

Referring to the several figures of the drawings, the structure therein illustrated comprises a shovel embodying a scoop 1 and a handle receiving portion 2, the shovel being of the type commonly employed for handling coal. A roller 3 is attached to the underside of the shovel in the region of the heel portion and is secured thereto by brackets 4 which may be secured to the shovel by bolts or rivets 5 in the manner shown in Fig.

One of the features of this invention is the provision of a roller member 3 which extends across substantially the entire width of the shovel to provide for the necessary contact of the roller with the floor over which it is manipulated irrespective of any irregularities which may be encountered.

By constituting roller 8 of a width corresponding to that of the shovel, the weight of the shovel and consequently theload on the roller is distributed over a relatively large bearing area, which in the improve,

ment illustrated comprises a rod 6 which is fastened or journalled in the brackets 4 as the case may be. I

roller shaft 3 and 6 are prefer ably a snug rolling lit to prevent any looseness such as would cause the roller to harm mer on its bearing to destroy the same and with this construction the roller is practically indestructible.

Instead of the engagement of the roller with the shaft 6, anti-friction bearing members may be utilized, but in any instance it is preferable that the roller 3 be substantially as long as the width of the shovel not only for the purpose of preventing the wear on the bearing parts but also to constitute the roller guide in the form of a full length support which effectively makes confact with the ground regardless of lumps of coal or other impediments over which it may ride. If the roller 8 were split up into short members, any one. of the rollers would be operative most of the time since the other roller would either enter a depression or be raised by loose coal in the manipulation of the shovel.

It is evident from the foregoing description of this invention that a coal shovel provided with a roller of the type herein described, facilitates the manipulation of the shovel particularly for coal mininmoperations and reatly lengthens the life of the shovel to which it is attached'by reducing or substantially eliminating the wear on its heel portion.

Although one embodiment of the invention has been herein illustrated and described, it will be obvious to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim herein as my invention:

1. The combination with a scoop shovel of a roller member extending substantially the entire width of said shovel, said roller being journalled on a shaft which is secured on'the underside and at the heel portion of the shovel.

2. The combination with a scoop shovel of a roller support extending substantially the entire width of the shovel, comprising a pair of brackets secured to the shovel at the heel portion thereof and a shaft secured in said brackets and constituting the roller support.

In testimony whereof, I have hereunto set my hand LANCELOT LINSLEIZ
